An instance of the BrandZ functionality, which provides non-global zones that contain non-native operating environments used for running applications.
An interface at Layer 2 of the OSI protocol stack, which is represented in a system as a STREAMS DLPI (v2) interface. This interface can be plumbed under protocol stacks such as TCP/IP. In the context of Oracle Solaris 10 zones, datalinks are physical interfaces, aggregations, or VLAN-tagged interfaces . A datalink can also be referred to as a physical interface, for example, when referring to a NIC or a VNIC.
The pool created by the system when pools are enabled.
See also resource pool.
The processor set created by the system when pools are enabled.
See also processor set.
Information about the disposition of resources within the resource pools framework for a given system at a point in time.
On SPARC based systems, the ability to reconfigure hardware while the system is running. Also known as DR.
A flexible way to record resource consumption on a task basis or process basis in the Solaris operating system.
A scheduling class, also known as FSS, that allows you to allocate CPU time that is based on shares. Shares define the portion of the system's CPU resources allocated to a project.
See fair share scheduler.
The root user or an administrator with the root role. When logged in to the global zone, the global administrator or a user granted the appropriate authorizations can monitor and control the system as a whole.
See also zone administrator.
Actions that apply to resource control values for every resource control on the system.
The zone contained on every Oracle Solaris system. When non-global zones are in use, the global zone is both the default zone for the system and the zone used for system-wide administrative control.
See also non-global zone.
The percentage of physical memory utilization on the system that will trigger cap enforcement by the resource capping daemon.
In the Projects and Tasks Overview chapter of this document, a reference to both LDAP containers and NIS maps.
A solaris branded non-global zone. Zones of other brands, such as the labeled and solaris10, or solaris-kz brands are not native zones.
The operating system level within a running native zone always matches the level of the global zone. Because the same kernel is used, no system-call translation is performed.
A virtualized operating system environment created within a single instance of the Oracle Solaris operating system. The Oracle Solaris Zones software partitioning technology is used to virtualize operating system services.
See zone administrator.
A software partitioning technology used to virtualize operating system services and provide an isolated, secure environment in which to run applications.
See resource pool.
A disjoint grouping of CPUs. Each processor set can contain zero or more processors. A processor set is represented in the resource pools configuration as a resource element. Also referred to as a pset.
The size of the resident set. The resident set is the set of pages that are resident in physical memory.
An aspect of the computing system that can be manipulated with the intent to change application behavior.
A daemon that regulates the consumption of physical memory by processes running in projects that have resource caps defined.
Fundamentally, an Oracle Solaris process. Process model entities such as the project and the task provide ways of discussing resource consumption in terms of aggregated resource consumption.
A functionality that enables you to control how applications use available system resources.
An exclusive subset of a resource. All of the partitions of a resource sum to represent the total amount of the resource available in a single executing Oracle Solaris instance.
A configuration mechanism that is used to partition machine resources. A resource pool represents an association between groups of resources that can be partitioned.
A process-bindable resource. Most often used to refer to the objects constructed by a kernel subsystem offering some form of partitioning. Examples of resource sets include scheduling classes and processor sets.
See resident set size.
A kernel thread that identifies infrequently used pages. During low memory conditions, the scanner reclaims pages that have not been recently used.
A representation of the way in which an administrator would like a system to be configured with respect to resource pools functionality.
In resource management, a process collective that represents a set of work over time. Each task is associated with one project.
A type of non-global zone in which all of the required system software and any additional packages are installed into the private file systems of the zone.
The size of the working set. The working set is the set of pages that the project workload actively uses during its processing cycle.
The rights of a zone administrator are confined to a non-global zone.
See also global administrator.
